Afraid I can't answer any of your questions, but if you are trying to figure out the logistics of matching pumps and bottles, you don't have to.
You can use whatever pump you prefer for expressing and transfer the milk to a different bottle 'family' for feeding. I used to use a Medela pump and feed with Avent bottles.
I would recommend Madela electric pump which is more comfortable. NUK electric pump is not good to me as the milkflow is not as much as Madela and it makes me painful when expressing the milk.
